The BBC has announced that Matt Smith, the actor who has played the Doctor in Doctor Who for the last four years, is leaving the show. Speculation will no doubt begin regarding his replacement. Given that the BBC first cast Christopher Eccleston for Doctor Who's revival (in his 40s in 2005), followed by David Tennant (in his 30s), and then Matt Smith (in his 20s), no doubt we'll be seeing a teenage high school student saving the universe this time next year (Justin Bieber perhaps?) At this rate, a small baby will be flying the Tardis within ten years' time. The entire Tardis will have to be rebuilt and scripts altered as the BBC tries to target the children's market. Baby Daleks and tiny Cybermen will battle the Doctor in an electronic pram. The Doctor's sonic screwdriver will be replaced by a sonic dummy.

In November last year the BBC quietly announced plans to adapt Susanna Clarke’s multi-award winning novel, Jonathan Strange & Mr Norrell, as a mini-series of 6 hour long episodes. The BBC broke the news so quietly in fact that we missed the announcement of what could well be a television highlight of 2014.

In the run up to the premiere of Season Three of Game of Thrones on 31 March 2013, HBO has begun the publicity campaign with a two minute in-production video. The featurette provides a glimpse behind the scenes of the forthcoming season and includes enthusiastic sound-bites from writers David Benioff and Dan Weiss (“This is the season that Dan and I have been anticipating from the very beginning”), interviews with established cast members, glimpses of new cast members, and a look at old and new locations.

I came across the sad news today that Michael O'Hare, the actor who played Jeffrey Sinclair in Babylon 5, has died at the age of 60. O'Hare also appeared in Law and Order and Tales of the Darkside, but no doubt will be best remembered for his role as Commander Jeffrey Sinclair in Babylon 5's first season. He also appeared briefly in seasons two and three.

The first season of the BBC's modern Sherlock Holmes adaptation, Sherlock, starring Benedict Cumberbatch as Sherlock and Martin Freeman as Watson, was one of the TV highlights of 2010. Sir Arthur Conan Doyle's classic Sherlock Holmes stories have never looked so good. Season two came to a close last year with a very tense cliffhanger, so it's good to know that a third season is definitely on its way. The bad news is that we will have to wait until September 2013 to watch it. While I didn't think the episodes that made up Season 2 were as good as the first, we're still talking about amazing television and excellent performances.

If you are a fan of HBO’s Game of Thrones series, you may also be a fan of the opening theme music composed by Ramin Djawadi. I consider it to be one of the best (if not the best) piece of theme music ever composed for a science fiction or fantasy TV show - it’s even better than the upgraded Battlestar Galactic’s opening credits theme music.

Have you been missing Doctor Who since the end of Season 7 Part 1? I know I have. Fear not, Matt Smith as the eccentric Time Lord "The Doctor" is returning for the remainder of the seventh season (Part 2) soon. A new Doctor Who trailer from the BBC reveals a great deal, including a new Dalek episode, a new companion and a Wild West visitation.

Season Two of HBO’s Game of Thrones has come and gone, and a third season is on the way in 2013. This time last year I was fully hooked, got by GoT you could say, and my enthusiasm for the series knew no bounds.

Broadly speaking there are three categories of change introduced in Season Two of HBO’s Game of Thrones. For the sake of brevity in an already overly long article, I'll restrict myself to a few examples, but many more could be provided.

Doctor Who is back in September this year with head writer Steven Moffat guiding the show once more. Karen Gillan and Arthur Darvill (Amy and Rory Pond) will leave and be replaced in the Christmas Special by newcomer Jenna-Louise Coleman.
